ShapeKeyGen is a Blender addon that generates the standard 52 ARKit blendshapes for rigged characters. It integrates with existing character setups, supporting AutoRig Pro, Rigify, and custom character rigs. The tool automates the creation of facial shape keys across multiple mesh parts, including eyes, teeth, tongues, and eyebrows, by grouping them into a registered collection. The addon provides controls to refine expression strength using location and rotation multipliers. It also features a reference panel that loads corresponding guide images in the Image Editor for specific frames or selected shape keys, assisting with manual adjustments in Sculpt or Edit mode. Additionally, it supports importing CSV animation data directly onto the character.
